Boruto entered the cave, which as it turned out for a moment was quite shallow

"Where did he disappear in such a narrow place, there must be a hidden passage somewhere?"

Searching the cave, the former shinobi accidentally found a hidden passage leading down, Boruto jumped there without thinking for a moment and after a while he found himself in a narrow corridor.

- What is this place?

Moving forward, a moment later Boruto left the building and it turned out that he was in another city full of people

- Where am I?

When the blond man explored the city, he accidentally bumped into someone and they fell over together, his eyes noticed some white material.

-Onee-san are you okay? - Some girl said, running up to them

Boruto looked up and noticed that his face was under some girl's skirt (she had short blue hair with her bangs dropped down half of her forehead), the girl was ashamed of the situation, as was Boruto, before the genin was to say something to another girl (she had orange hair braided in a braid, green eyes) grabbed Boruto by the collar lifting it up

- What were you pervert doing to my sister?

"Me, this ... it was an accident, I swear." he tried to explain himself

-You think I'll believe you, everyone says so.

-Onee-san calm down telling the truth, I actually ran into him because I was thinking, it's not his fault.

The girl looked at her sister and released the blonde

- This time I forgive you, but if you do some perverted thing to my sister again, you will be a corpse - she threatened to which Boruto only nodded his head swallowing saliva

- My name is Hisako and this is my sister Yakira, I apologize for her behavior

- No problem, what kind of city is this anyway?

-They are called the Underground City. You see the people who are here have experienced the war, their hometowns have been destroyed. Hayaro-sama built this city with them in mind to protect them from future wars. - Hisako explained

- I understand, where can I find this whole Hayaro?

-Come follow me, I'll show you

-You are crazy Onee-chan, why do you want to lead the stranger to Lord Hayaro?

-Since he can seek help, what is your name anyway?

-Boruto.

The sisters took Boruto to the administration building where the city's leader resides

"It is here, Lord Hayaro's office is on the third floor.

"Thank you," said Boruto going inside

-You think showing him this place was a good idea? - Yakira asked

Hisako stared as Boruto entered the building for a moment, only when her sister poked her in the arm she touched herself

- What? I think so.

Boruto at that time arrived in front of the city's chief's office

"Hayaro-sama, I managed to get the crystal," Fujiro announced, showing the obtained item

"Perfect, now my father's city will have no choice but to turn to the capital for help
